fIMPRovEt/mlv'r :N Panna-CUTTING MACHINES.

The ,Schedule referred to iin-,these Letters Patent and making part Of th 5me To all whom it may oncem Y Be it-known that I, ARTHUR W. CURRIER, of the city of Grand Rapids, countyof Kent, and State of Michigan, have invented 'certain new and useful lmprov'ements in Machines forGntting Paper; and I do hereby declare that the following is a full, clear, and

l exact-description thereof, nreference being had to the motion, while being forcedthrough the paper to be operated upon.'

To'enable others, who are skilled in the branch of business to which he'manufacture of my invention belongs, to make, the same, I' will proceed to particularly describe its construction. p

The machineproper `is made of cast-iron or `.like suitable material,.save the knife, which is of steel, and 4rests upon and is fastened to asolid and substantial frame or stand of wood or iron, to which frameit is attachedby bolts, as shown.

rlhe knife a is an ordinary straight steel knife,

i screwed `firmly to the knife-plate b b, which is rah` beted-on the backv side to receive it. rlhis plate is made of cast-iron, smoothly planed to about an inch .in thickness, and provided-with two diagonal'slots, g

g, one at each end,.placed at an angle of about sixty degrees from a perpendicular line.

O C are two cast-iron posts or standards, connected together by the brace e and resting down upon the frame beneath. i.

These posts are each cast in two pieces, and between them is left a slotor aperture sufficiently wide to allow thev` knifeplate l) b to play easily between them.

About ten inches up from the stand, in an ordinarysized machine, is placed in each post, a bolt, either` with or without a friction-pulley thereon, upon which the knife-plate is hung by means of the slots g g.

At the upper rightfhand corner of the knife-plate, as shown in tig. 1, it is provided with a segment, so called, or toothed edge, parallel with the slot g, immediately beneath it, which segment engages with and is operated by the'cog-wheel k, tig. 2, which is rests upon and holds the paper.

'may be used in squaring or sizing-paper.

' hidden from view in fig'. 1 by the intervening postor standard, the shaft to which it is attached, however,

being shown in tig. l by d.

The" gearing ofthe machine is shown more fully by iig. 2, and consists of hand-wheel l, set of bevell gearing mand n, straight gearing `O`and lr, and the cog-wheel k before mentioned.

'lhis gearing is arranged Aas exhibited in iig. 2', to communicate motion from the hand-wheel l to theknfe-plate b b, and toy so multiply and increase the power applied atthe hand-wheel astoforce the knife rmly and steadily through the paper to be cut.

The posts c c, as shown in fig. 2, are connected hy a brace, e, and this brace, in connection with the hand wheel and screw u, forms a clamp for holding the -paper while being cut, the lower end of the screw op'- erating inan expanded surface of wood or iron which A gauge, W, adjusted by means of the set-screw as,

The upper' ends of the slats g g may he depressed to a horizontal line, if desired, to hold the knifefrom a further downward movement after tllepaper is cut; hut ysuch depression is not claimed as a part of my invention.

The front posts c c and brace e should be cast in one piece, andv so ofthe rear posts and brace.

' Iii-using my invention, the paper to be cut should be firmly held and .pressed together by the clamp abo-ve described under the edge of the knife, and the knife then forced down through it by means of power applied at the hand-Wheel Z. should be again elevated bya reverse movement of the hand-wheel.

The diagonal passage of the knife through thepaper and its` steady uniform motion serve tol cnt'the .paper very smoothly and with but a slight application 'of power at the hand-wheel.

Having thus described my invention,

Wha-t l claim to have iihvented, and desire to secure by Letters Patent of the United States, is

rLhe arrangement and combination of the slotted knife-plate b b, so hung upon pulleys as to pass ob- -liqu'ely upward or downward when moved,'and the toothed edge or segment x', pinion k, gearing O, lr, n, and m, and hand-wheel l, all constructed and operating as and for the purposes above set forth.
